Now, I am stuck to Chrome. FB upload is good and Hotmail works properly. What are you using? The chart above shows that Chrome is still catching up. But IE still account for almost half of all browsers, for obvious reason.
I am hoping that Chrome can be made "portable" like Firefox, ie, run from pendrive.
p/s: After posting this blog, I found that there is a portable version which can be downloaded from http://portableapps.com/. They have other software as well which are "portable", ie, installable on pendrive.
